M550 Impedance Calibrator
Bank of fixed resistance, capacitance and inductance standards with defined frequency characteristic up to 1 MHz for automated calibration of LCR meters.
- Automated RCL calibration
- Calibration data from 20 Hz to 1 MHz
- No need for pen and paper method
Idea behind M550 Impedance Calibrator is to replace countless single value LCR standards with one calibrator
that can switch between the standards like a CD changer in your car. The calibrator contains stable and
temperature independent resistance standards, partial capacitance standards and partial inductance standards,
simulated by RC T-type passive network. Calibration values of both complex parameters of partial standards
are displayed on large LCD screen in preselected pairs of parameters as well as voltage, current and frequency
readouts from built-in test signal meter. OPEN and SHORT reference positions are available as well.
Easy recalibration system offers either full recalibration in all spot frequency points or simplified
offset calibration. History of calibration values of partial standards at reference frequency 1 kHz can
be easily recalled.
Calibration domain
M550 was designed for calibration of LCR meters in frequency range up to 1 MHz. The philosophy of M550 is based on remote control and automated calibration. For this reason, the calibrator is equipped with RS-232 and GPIB interfaces and of course, supported in CALIBER/WinQbase calibration software.
